| Abstract: | Ultrashort Radial Radial System (URRS) can turn vertical to level in shaft section of 0 3m radius, make the horizontal well enter the target stratum accurately. By using the high_pressure jet, the hole of horizontal well is formed. URRS overcomes the difficulty of exerting pressure and solves a series of drill pipes rotary problems, and reduces the accident in the well and improves the speed of the well drilling. According to the detailed introduction to the basic principle and the mining method of URRS, USSR, as a new technical measure,is imported to mine gas so as to improve extracting quantity. |
